In order to elucidate the transmission and dispersion routes used by the myxozoan parasite Enteromyxum scophthalmi Palenzuela, Redondo et Alvarez-Pellitero, 2002 within its host (Scophihalmus maximus L.), a detailed study of the course of natural and experimental infections was carried out. Purified stages obtained from infected fish were also used in in vitro assays with explants of uninfected...

Giardia, a protozoan parasite, resides in the small intestine in man. This parasite damages the mucosal intestinal surface and in severe cases produces malabsorption and it may also affect mineral absorption, especially zinc. In this study a total of 118 infested and 43 non-infested persons as a control group were selected. From each patient a 5 ml blood sample was obtained. The serum was ...

To determine geographical patterns of natural parasite infections among wild rodents, a total of 46 wild rodents from 3 different localities in northern Gangwon-do (Province), Korea were examined for intestinal parasite infections. Along with nematodes such as hookworms and Syphacia spp., Plagiorchis muris (2 specimens) (Trematoda) were collected from striped field mice, Apodemus agrarius. In a...

OBJECTIVE In this study prevalence of intestinal parasite agents was investigated among elementary school students in the Mugla city centre. METHODS Only 663 relatives among 3560 students allowed us to investigate and obtain fecal specimens of the students. Specimens were examined by native and lugol staining. Repeated samples were requested from suspected cases and evaluated. RESULTS Intes...

Prevention of intestinal infection by Entamoeba histolytica would block both invasive disease and parasite transmission. The amebic Gal/GalNAc lectin mediates parasite adherence to the colonic surface and fecal anti-lectin IgA is associated with protection from intestinal reinfection in children. We tested if vaccination with the E. histolytica Gal/GalNAc lectin could prevent cecal infection in...

BACKGROUND Parasitic infections affect tens of millions of pregnant women worldwide, and directly or indirectly lead to a spectrum of adverse maternal and fetal/placental effects. The objective of this study was to assess the prevalence of intestinal parasite infections and associated risk factors among pregnant women attending antenatal care center in Felege Hiwot Referral Hospital, Bahir Dar ...

  In order to determine prevalence of Echinoccocus and other intestinal helminths infection one hundred stray dogs were examined in Mashhad area, Khorasan province of Iran. Helminths were collected from intestinal contents obtained at the time necropsy. Ninety one percent of the dogs were infected by different helminths. The prevalence of Echinococcus granulosus was (22%). Eighteen (81%) of inf...

Blastocystis hominisis a common parasite implicated in a variety of intestinal problems. Oral-faecal route of transmission has been postulated but the cystic phase which is presumably the infective stage of the parasite, has only recently been described using electron microscope. However, little information is available on the light microscopic morphology of the cyst. There are two possible rea...

Background Sublethal parasite infections may cause mortality indirectly by exposing the host to predation. The best known example of this among birds is red grouse in which caecal nematode infection causes increased risk of predation and can even affect population dynamics [1]. Intestinal helminth parasites are common in forest grouse, capercaillie Tetrao urogallus, black grouse Tetrao tetrix a...

background: intestinal parasites of humans are important health problems of most communities, especially those situated in tropical and subtropical areas. this study was carried out in rural population of mazandaran province, northern iran, during 2004-2005, with the purpose of achieving a better understanding of the distribution of intestinal protozoan parasites in this province. methods: a to...
